So I have heard of people making changa, but has anyone ever dissolved some pot oil or some bubble hash in some iso, done the same with some quantity of DMT and then mixed the two and evaporated?

this seems like it would help protect the DMT from oxidizing as well as providing a very good medium for smoking in perhaps more regular dosages then changa.

Any thoughts? I think this would work quite well

I have mixed chopped up cannabis flowers and spice together in iso and evapped it to make a cannabis changa. It worked well, and tasted good..I dont really like mixing the 2 anymore though but I think you're idea would work.

I've acutally stopped mixing the two. I don't much care for the effects of the two combined, but I guess it could work...maybe not so much with hash, as it takes a while to smoke, but MJ changa would work fine.

Well really like i said I am already aware of Changa, the idea is more to coat the DMT in hash oil so that it is more air resistant. It really depends on what ratio of DMT you put to the hash that will determine how long it takes to smoke it, it just seems like it could be less wasteful then changa, though admittedly SWIM has never mixed DMT with anything. I just think it could be a better medium for smoking as well as transportation, with more evenly distributed DMT then with Changa.
If pot isnt your thing, there are any number of resinous extracts that could work.

Perhaps DMT could be combined with the soft extract of Salvia? This would probably be pretty wasteful though if taken sub-lingually
